National and international vendors will set up shop downtown in Market Square, and the square will be illuminated with little white lights and adorned with holly.

Santa Claus and his elves were at the PPG Place Wintergarden for the big announcement Thursday morning.

"We're going to have tour buses. This is going to become an event that people from all around the region are going to want to come into the city," said Morgan O'Brien, CEO of Peoples Natural Gas, which sponsors the event.

The Pittsburgh Downtown Partnership said the Holiday Market will be open daily from 11 a.m. to 8 p.m, starting Nov. 24 and ending Dec. 23.
